Just deleting it is dangerous! How to "completely erase" disk data

2025/12/3 Edited to

... Read morePCを売る前・人に譲る前・廃棄する前にやるべきことって、実は「初期化したからOK」だけだと不安が残ります。私も最初はWindowsの初期化=完全に消えると思っていたのですが、削除/フォーマットと同じで“見えなくなるだけ”のケースがあり、復元ソフトで戻される可能性があると知って対策しました。 ■「初期化するとどうなる?」(Windows) Windowsの「このPCを初期状態に戻す」は、アカウントやアプリを消して再セットアップ状態にする機能です。ただし設定次第で安全性が変わります。 ・「個人用ファイルを保持する」→データが残るので売却/廃棄には不向き ・「すべて削除する」→基本は消えるが、復元リスクをゼロにするなら追加対策推奨 ・「ドライブを完全にクリーンアップする(ドライブのクリーニング)」が選べる場合→上書きが走るので、売却・廃棄向け ※Windows7/8だと表記や手順が違うことがありますが、考え方は同じで「削除+上書き」までやるのが安心です。 ■完全消去=“上書き”がポイント(ゼロ書き/ランダム/DoD/Gutmann) 復元不可レベルを狙うなら、データ領域に上書きをかける方式が定番です。上書き方式には、ゼロ書き、ランダム書き、DoD、Gutmannなどがあり、時間はかかるほど強力になります。私は「絶対に残したくないデータが入っていたか?」で選びました。 ・急ぎ/一般用途:ゼロ書き or ランダム書き ・不安が強い:DoDなど複数回上書き ・最終手段:Gutmann(時間がかなりかかる) ■SSDの完全消去は“HDDと同じ感覚”でやらない SSDは仕組みが違うので、延々と多重上書きをすると寿命面が気になることがあります。可能ならSSD向けの「Secure Erase」やメーカー/ツールのSSD完全消去機能を優先すると安心です(対応しているツールを選ぶのが大事)。 ■USBメモリ/外付けHDD/CD-Rの注意点 ・USBメモリ/外付け:PC本体と同様に“上書き消去”が有効。暗号化していた場合は鍵の削除も有効です。 ・CD-R:基本は書き換えできないので「初期化」はできません。個人情報があるなら物理破壊や専門回収を検討しました。 ■ディスククリーンアップは“完全消去”ではない Windowsのディスククリーンアップは不要ファイル削除が中心で、売却前の情報漏洩対策としては不足になりがちです。私は「整理」ではなく「消去(上書き)」を目的に手順を分けました。 ■私がやった売却/処分前チェックリスト 1) ブラウザ履歴・保存パスワード削除(念のため) 2) Microsoftアカウント/Apple ID等のサインアウト、デバイス解除 3) App Store系や各種アプリの連携解除(必要なら) 4) Windows初期化(売却なら“ドライブのクリーニング”付き) 5) さらに不安なら、消去ソフトで上書き or SSDならSecure Erase系 6) 可能なら別PC/USBから起動して空き領域も含めて確認 「データ 完全 消去 は 不 可能?」と不安になる気持ちはわかりますが、現実的には“復元ソフトで戻せない状態”まで持っていく手段はあります。売却・無料回収・廃棄に出す前に、初期化だけで済ませず、目的に合った完全消去を選ぶのが一番の安心でした。
